In the D3D12Multithreading example, shadow map sampler shouldn't be using D3D11_TEXTURE_ADDRESS_CLAMP mode. #882
Description
Any objects outside the frustrum of light camera should be in shadow, and D3D12_TEXTURE_ADDRESS_MODE_BORDER should be used here otherwise its no use setting BorderColor for D3D11_TEXTURE_ADDRESS_CLAMP.
Original code:
D3D12_SAMPLER_DESC clampSamplerDesc = {};
clampSamplerDesc.Filter = D3D12_FILTER_MIN_MAG_MIP_POINT;
clampSamplerDesc.AddressU = D3D12_TEXTURE_ADDRESS_MODE_CLAMP;
clampSamplerDesc.AddressV = D3D12_TEXTURE_ADDRESS_MODE_CLAMP;
clampSamplerDesc.AddressW = D3D12_TEXTURE_ADDRESS_MODE_CLAMP;
clampSamplerDesc.MipLODBias = 0.0f;
clampSamplerDesc.MaxAnisotropy = 1;
clampSamplerDesc.ComparisonFunc = D3D12_COMPARISON_FUNC_ALWAYS;
clampSamplerDesc.BorderColor[0] = clampSamplerDesc.BorderColor[1] = clampSamplerDesc.BorderColor[2] = clampSamplerDesc.BorderColor[3] = 0;
clampSamplerDesc.MinLOD = 0;
clampSamplerDesc.MaxLOD = D3D12_FLOAT32_MAX;
m_device->CreateSampler(&clampSamplerDesc, samplerHandle);
Should be modified to:
D3D12_SAMPLER_DESC clampSamplerDesc = {};
clampSamplerDesc.Filter = D3D12_FILTER_MIN_MAG_MIP_POINT;
clampSamplerDesc.AddressU = D3D12_TEXTURE_ADDRESS_MODE_BORDER;
clampSamplerDesc.AddressV = D3D12_TEXTURE_ADDRESS_MODE_BORDER;
clampSamplerDesc.AddressW = D3D12_TEXTURE_ADDRESS_MODE_BORDER;
clampSamplerDesc.MipLODBias = 0.0f;
clampSamplerDesc.MaxAnisotropy = 1;
clampSamplerDesc.ComparisonFunc = D3D12_COMPARISON_FUNC_ALWAYS;
clampSamplerDesc.BorderColor[0] = clampSamplerDesc.BorderColor[1] = clampSamplerDesc.BorderColor[2] = clampSamplerDesc.BorderColor[3] = 0;
clampSamplerDesc.MinLOD = 0;
clampSamplerDesc.MaxLOD = D3D12_FLOAT32_MAX;
m_device->CreateSampler(&clampSamplerDesc, samplerHandle);
